Holder for portable electronic device

ABSTRACT

A holder includes a cover, a base, and a charging module. The cover includes a battery, and the base is foldably connected to the cover. The charging module includes a main charging coil and a power supply. The battery and the main charging coil are electrically connected to the power supply. A first proportion of a current from the power supply charges the battery, while a second proportion of the current from the power supply sends current to the main charging coil. The main charging coil charges a portable electronic device received in the holder.

BACKGROUND Technical Field

This disclosure relates to holders for portable electronic devices, andparticularly to a holder used for charging different portable electronicdevices.

Many people carry portable electronic devices, such as tablet computersand mobile phones. When a tablet computer is used to read an eBook or towatch a video, power of the tablet computer is used up quickly.Additionally, mobile phones need to be charged often. However, it isinconvenient to carry two different chargers for the tablet computer andthe mobile phone.

Therefore, there is room for improvement within the art.

DETAILED DESCRIPTION

FIG. 1 shows a holder 100 used for receiving a first portable electronicdevice 60 and a second portable electronic device 70. In this exemplaryembodiment, the first portable electronic device 60 is a tabletcomputer, and the second portable electronic device 70 is a mobilephone, but the disclosure is not limited thereto.

The holder 100 includes a cover 10, a base 30, and a charging module 50.The base 30 receives the tablet computer 60 and the mobile phone 70. Thecover 10 is foldable relative to the base 30 to cover the tabletcomputer 60. The charging module 50 charges the tablet computer 60 andthe mobile phone 70.

The cover 10 defines a plurality of grooves 102 substantially parallelto each other to position the tablet computer 70 received in the base 30at different angles relative to the cover 10. A battery 11 is receivedin the cover 10 and has a holder port 13 exposed from the cover 10. Thebattery 11 charges the tablet computer 60 and the mobile phone 70through the holder port 13.

The base 30 includes a main plate 31 and a support plate 35 foldablerelative to the main plate 31. One surface of the main plate 31 has twofirst latching walls 312 at opposite sides of the main plate 31,respectively, and a second latching wall 314 between the two firstlatching walls 312. The first latching walls 312 and the second latchingwall 314 cooperatively define a first receiving space 310 on a firstsurface of the main plate 31. The first receiving space 310 receives onepart of the tablet computer 60. One of the first latching walls 312defines a through hole 37. Another surface of the main plate 31 has areceiving portion 33. A size of the receiving portion 33 corresponds toa size of the mobile phone 70. A second receiving space 331 is definedin the receiving portion 33 for receiving the mobile phone 70. Oppositesides of the support plate 35 are foldably connected to the main plate31 and the cover 10, respectively. When the tablet computer 60 needs tobe supported at an angle relative to the cover 10, one part of thetablet computer 60 is received in the first receiving space 310, whilethe other part of the tablet computer 60 is received in one of thegrooves 102. The support plate 35 is angled relative to the main plate31 and the cover 10 for holding the tablet computer 60.

The tablet computer 60 has a first port 61 and a second port 63. Themobile phone 70 has a third port 71. When the tablet computer 60 isreceived in the first receiving space 310, the through hole 37 isaligned with the first port 61, so that the first port 61 of the tabletcomputer 60 is exposed from the holder 100. A first wire 15 electricallyconnects the holder port 13 of the battery 11 to the second port 63 tocharge the tablet computer 60. A second wire 17 electrically connectsthe first port 61 to the third port 71 to transmit the energy of thetablet computer 60 to the mobile phone 70.

Referring to FIG. 1, the charging module 50 includes an arraying cable51, a main charging coil 53, and a power supply 55. The arraying cable51 electrically connects the charging coil 53 and the battery 11 to thepower supply 55. The arraying cable 51 has a first arraying cable 511, asecond arraying cable 513, and a third arraying cable 515. The firstarraying cable 511 is connected to the third arraying cable 515 forelectrically connecting the main charging coil 53 to the power supply55. The second arraying cable 513 is connected to the third arrayingcable 515 for electrically connecting the battery 11 to the power supply55.

Referring to FIG. 3, the tablet computer 60 has a first secondarycharging coil 65, and the mobile phone 70 has a second secondarycharging coil 75. When the power supply 55 is provided, one firstproportion of a current from the power supply 55 is sent to the maincharging coil 53, and the current from the main charging coil 53 iscoupled to the first secondary charging coil 65 and the second secondarycharging coil 75 by electromagnetic coupling for charging the tabletcomputer 60 and the mobile phone 70, respectively. A second proportionof the current from the power supply 55 charges the battery 11. When thepower supply 55 is not used, the tablet computer 60 and the mobile phone70 are charged by the battery 11 via the first wire 15 and the secondwire 17, respectively.
